Neoplasia is an important topic. You will definitely encounter patients with neoplasms, either benign<\/strong> or malignant<\/strong>. Pathology plays a central role in the understanding of neoplasia.<\/p>\n

Imagine this:<\/strong><\/p>\n

Mr Chua is a 67 year old smoker with a chronic cough and a history of weight loss.<\/p>\n

CT scan<\/strong> of the thorax reveals a left lung mass<\/strong>.<\/p>\n

\"\"<\/p>\n

A tissue sample (biopsy)<\/strong> is obtained and sent to the pathologist. The pathologist examines the tissue microscopically\u00a0and writes a report (eg. benign or malignant tumour, tumour type<\/strong>). The clinician needs\u00a0the report to decide on the next step. If the tumour is malignant, the next step is to find out the extent of disease (stage)<\/strong>.<\/p>\n

Diagnostic imaging<\/strong> is of key importance\u00a0in the staging of malignant tumours. Once tumours are properly staged, decisions can be made on whether they can be removed surgically or whether chemo- or radiotherapy is required.<\/p>\n

After the malignant tumour is removed, the pathologist again assesses the tumour and gives a ‘how bad is it’\u00a0report (prognosis<\/strong>), whereupon the decision on further treatment is made.<\/p>\n

But first things first<\/strong> <\/em>– you need to understand the inner workings of the cells in order to understand the process of neoplasia – what is neoplasia, how does it start; how to name, recognise and classify it<\/strong> before you can understand the effects on the patient. Later, when you are in the clinics and wards, you will learn how it is diagnosed, assessed and treated.<\/p>\n

As you read more, you will discover some hidden exercises and quizzes<\/em><\/strong>.<\/p>\n\t\t\t\n\t\t\t\t\t\t\tI. Approach to Neoplasia\n\t\t\t\t\t<\/a>\n\t\t\t\n\t\t\t\t\t\t\tII.
